Tooth injury by chewing a soft drink can's ring: a case report.

Abstract

This article describes a 28-year-old male patient's habit of chewing the aluminum ring of soft drink cans, with harmful consequences: broken cusp, dental attrition and craze lines. Although the reported dental damage is similar to that seen in oral piercing and wearing metal ornaments, the reported habit was unknown to the dental team in the 10 years preceding the event of cusp breakage. Dental practitioners should ask patients about their lifestyles and habits before occurence of such a complication, which has potential to affect oral integrity.
